TANK-COVER,

Application filed September 7, 1909. Serial No. 516,589.

To all whom it may concern:

Be it known that I, ANDREW A. KnAMER, a citizen of the United States, residin at Kansas City, in the county of-W and otte and State of'Kansas, have invente certain new and useful Improvements in Tank-Covers; and I do declare the following to be a full, clear, 'and exact description of the 111- Vention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings and to the figures of reference marked thereon, which form a part of this specification.

My invention relates to metal tanks and more particularly to a sectional cover therefor.

Tank covers heretofore have usually been made in a single piece by cutting the material into sectors of the proper shape and riveting the separate pieces together. \Vhen so formed, the covers have been difficult to handle and ship and are often damaged be.- fore they are finally fitted to a tank.

It is the object of my invention to provide a tank cover which may be made up in sections at the factory and easily and quickly assembled by the purchaser. In accomplishing this object I have provided the improved details of structure hereinafter described and pointed out in the claims, reference being had to the accompanying drawings, in which:

Figure I is a broken plan view of a tank cover constructed according to my invention. Fig. II is a vertical section of the same. Fig. III is an edge view of adjoining cover sections. Fig. IV is an enlarged perspective view of one of the sections. Fig. V is an edge view of the cap strip and portions of the cover sections upon which it is mounted. Fig. VI is a detail view of the cap strip.

Referring more in detail to the parts The cover is made up of sheet metal sections 1, which, when the cover is round, are approximately sector shaped in contour and are cut off at their inner ends to leave room for edge rolls and to provide an opening at the apex of the cover. One edge of each cover section is rounded up to form the projecting roll 2, and the opposite edge is turned upwardly at substantially a right angle to the section body and then rounded to provide the receiving roll 3, the edge of the roll 2 being faced downwardly toward its turning point to provide a hook lip 2 and the roll 3 being faced upwardly and outwardly from the angling portion, to form the grooves 3, thereby forming spirals adapted to hold against each other when the roll 2 of one section is projected into the roll 3 of another section. One section of the cover is curved the same at both edges so that it may have a roll 2 at each side.

9 designates a cap strip having a downwardly turned roll 10 at each edge which is bent under the body of the strip to enable it to combine with the rolls 2 of adjoining cover sections. The cap strip is used to connect the first and last placed sections of the cover as it would be impossible to join the edges of these sections directly, owing to their triangular formation.

4 designates a metal cone which is adapted to project through the opening in the apex of the cover and bear againstthe under surfaces of the cover sections. Gone 4 has an aperture in its apex and has a toggle?) provided with an aperture that registers; with that in the top of the cone.

6 designates an ornamental cap which is adapted to cover the opening in the apex of the cover and is provided with a base flange- 7 which seats on the upwardly projecting; rolls 2. 3 of the. cover section. The flange T is of sutlicient width to prevent rain from driving into the cover opening between the same and the cover body, and, being sup-- ported above the body, allows a circulation of air through the cover opening.

8 designates a bolt which is passed through the ornamental cap and through the cone L- and toggle 5 and has a nut adapted to) tighten against the cross bar so that the cap may be held tightly on the cover over the opening.

With a tank cover constructed as de-- scribed, the cover ma be delivered in sections to the point W ere a tank is to be erected. I

To assemble the cover, two of the sections 1 are moved together so that the roll 2' of one section is projected into the roll 3,015" the other section, with the lip 2 nested within the groove 3'. Succeeding sections are added in the same manner until the lastsection is ready to be placed, whenthe section having the double roll 2 is placed in position and joined to the roll 2 of the first cone section by means of the cap strip.

To form the cover into a cone, a space equal to about the width of one of the cover sections is left in the body when it is fiat, and'the body bul ed upwardly to bring the edges together be ore the application of the cap strip. After the cone is shaped, the cone and cap parts are attached as heretofore described.

It is apparent that a cover may be formed in any convenient number of sections, and that the caps 6 may be of difierent designs.

Having thus described my invention, what I claim as new therein and desire to secure by Letters-Patent is 1. A tank cover formed'in sector shaped sections, each section having upwardly rolled edges telescoping with the rolled edges of adjoining sections, said sect-ions being terminated at a distance from the center of the cover to provide an opening, a member projected into the opening and bearing against 20 the under surface of the cover, and a cap covering the openin and having a flange seated on the rolled edges of the cover sec:

tions, the cap being bolted to the under member, for the purpose set forth.

2. A sheet metal tank cover, comprising assembled sector shaped sections having slidably engaged radial'joints, therebeing a toggle opening'in the cover; a hollow sheet metal cap mounted upon the apex of the cover, a depending bolt fastened to the cap and passing through the apex of the cover, and a toggle supported by the lower end of the bolt within the cover.

In testimony whereof I afiix my signature in presence of two Witnesses.

ANDREW A. KRAMER.
